Frequently asked questions
How do I reply to a customer conversation using the AI?
You can use the add_reply tool. Just provide the Conversation ID and the body of your message, and the agent will send it to the customer via FreeScout.
Can I update the status or assignee of a ticket?
Yes! Use the update_conversation tool. You can change the status (active, pending, closed, spam) or provide an assignee_id to route the ticket to a specific team member.
Is it possible to add internal notes that the customer won't see?
Absolutely. Use the add_note tool to post internal comments on a conversation. These are visible to your team in FreeScout but are never sent to the customer.
How does LangChain connect to MCP servers?
Use langchain-mcp-adapters to create an MCP client. LangChain discovers all tools and wraps them as native LangChain tools compatible with any agent type.
Which LangChain agent types work with MCP?
All agent types including ReAct, OpenAI Functions, and custom agents work with MCP tools. The tools appear as standard LangChain tools after the adapter wraps them.
Can I trace MCP tool calls in LangSmith?
Yes. All MCP tool invocations appear as traced steps in LangSmith, showing input parameters, response payloads, latency, and token usage.
